The various schools of poker can have high tuitions. And no assurance you will graduate with any sort of knowledge. I am talking about playing poker with real people. Paying for training from a coach is a different matter.
Finding a coach that can match their advice to your skill levels is no small thing. Few trainers can make that leap - rather they teach their class and hope it works for you.
